hi

i am interesting where i can find some sort of "most common" electronic
circuit diagram of typical PC motherboard, no matter if it is S478 or S462
type...

i am interesting in troubleshooting motherboards by electronic way...like;
checking usual malfunctioning resistors, transistors(fets) or regulators
and DC2DC convertors and regulators...

about measuring and replacing capacitors i already know (been there-done
that)...i want to get a bit deeper into repairing motherboards...

also could be some help if you point me to some sort of block diagram wich
shows usual and most common way of power supply circuits on mobo's and other
circuits wich are usualy goes down, get burned, malfunctioning...etc...

i got mostly all necessary equipment for measuring (multimeters digital and
analog, ESR meter, LFC meter, R/C meter..etc..), also tools like Weller iron
solder Magnastat inc. hot air soldering station...except scope wich is very
old (1969.) and got only 8MHz (Hameg HM207)..so its not so usefull, but it
works fine for svereal basic tests...

just for info; i am hobbist in electronics (beside HAM radio operating)

thanks a lot in advance for any kind of help and tips&tricks...
